WebThioglycolic acid can be prepared by the action of sodium sulfhydrate on sodium chloroacetate and by electrolysis of dithioglycolic acid from sodium sulfide and sodium chloroacetate. It is also formed by heating chloroacetic acid with potassium hydrogen sulfide. Thioglycolic acid and its salts and glyceryl esters are not known to occur naturally.
